I am looking for a gunsmith trick way to machine a 1.25 dia straight blank into a tapered octagon. Would like .600 at the muzzle and about 1.06 at the breech, its about 26in long. I have a bridgeport with a long table,indexing head with an adjustable center and need help with sine, indexing and the best way that smiths have been doing oct barrels for years. Any help will be appreciated
Thanks, turbo
